The sleeve comprises one or more protrusions extending towards the interior of the sleeve, and the support device comprises one or more recesses adapted for receiving the one or more protrusions. The outer container, the sleeve, and the support device are securely engaged. The outer container is made of a biodegradable and compostable fibre material such as, but not limited to, polylactic acid, bamboo, bagasse, or a combination thereof. At least a part of the sleeve and support device is made of a biodegradable and compostable material such as, but not limited to, polylactic acid, or a combination of biodegradable and compostable materials. Also disclosed is a method of manufacturing the beverage cartridge, and use of the support device in the manufacture of the beverage cartridge.

TECHNICAL FIELD

The present disclosure relates to a beverage cartridge such as, for example, a compostable beverage cartridge for single-serve use. The present disclosure further relates to methods of manufacture and uses thereof.

BACKGROUND

The popularity of single-serve beverage cartridges has grown rapidly over the past decade, as more and more people trend towards the desire to brew or prepare beverages quickly and in single-portion quantities.

Beverage cartridges for single-serve use typically comprise a container, a filter, and a cover. The container will usually comprise an opening on the top of the container, and a hollow cavity within which and across which a filter is disposed. The filter separates the container into two chambers: a first chamber occupying the space within the container between the filter and the opening of the container, the first chamber for holding dry beverage ingredients such as, but not limited to, coffee, tea, or cocoa, for a single beverage serving; and (ii) a second chamber occupying the space within the container between the filter and the base of the container, the second chamber being on the opposite side of the filter to the first chamber. The cover is disposed over the opening of the container, and keeps the dry beverage ingredients within the container.

In practice, a single-serve beverage cartridge is placed into a compartment of a brewing machine. The machine is activated such that a fluid injector penetrates the cover of the cartridge and a fluid extractor penetrates the base of the cartridge. The fluid injector injects a brewing medium (e.g. hot water) into the first chamber for extracting flavours from the ingredients. The brewing medium containing the extracted flavours percolates through the filter and into the second chamber. The brewing medium containing the extracted flavours is then extracted by the fluid extractor and eventually dispensed as a drinkable beverage.

Currently, the container of a beverage cartridge for single-serve use is typically made from petroleum-based plastic materials which are neither biodegradable nor compostable. The cover is typically made of a metal foil or a metal foil laminate which is glued to the top of the container. Generally, neither the metal foil of the cover nor the glue affixing the cover over the opening of the container is biodegradable, compostable or made from readily renewable resources. As a result, non-biodegradable and non-compostable beverage cartridges typically end up in landfills, thereby at least contributing to environmental concerns associated with disposal of trash.

Manufacture of Beverage Cartridge 300

Using the beverage cartridge 300 depicted in FIG. 3 as an example, container 310 is manufactured. The sleeve 320 is manufactured by vacuum forming. The support device 330 is manufactured by injection molding.

As previously described and according to the embodiment depicted in FIG. 3(a), the shape of the sleeve 320 is complementary to the shape of the container 310. Referring to FIG. 7, the sleeve 320 is inserted into the container 310 such that: (i) top perimetral ledge 321 of sleeve 320 engages top perimetral ledge 312 of container 310; and (ii) outer surface 320 a of sleeve 320 faces inner surface 310 b of container 310. The outer surface 320 b of sleeve 320 is slightly melted, the sleeve 320 is press-fitted against the inner surface 310 b of container 310, and the sleeve 320 is then rapidly cooled, thereby adhering the sleeve 320 to the container 310. The inner surface 320 b of sleeve 320 thereby forms the inner surface of beverage container 300. Without wishing to be bound by theory, it is believed that the melted outer surface 320 b of sleeve 320 interacts with the biodegradable and compostable polymeric fibres of container 310, thereby providing a secure engagement between the sleeve 320 and container 310.

The filter element (not shown) is coupled to the support device 330. The first surface 333, the surfaces of extensions 337, 338, 339 and platform 341 are slightly melted. The body of the filter element is inserted through the channel 335 until the side of the body of the filter element is in contact with the melted surfaces of extensions 337, 338, 339 and the bottom of the body of the filter element is in contact with the platform 341. The perimetral ledge of the filter element is placed in contact with the melted first surface 333. The filter element is pressed against the melted surfaces of extensions 337, 338, 339 and platform 341, and the support device 350 is then rapidly cooled, thereby securely engaging the filter element to the support device 330. The hot melt temperature is kept below a temperature that would damage, burn or otherwise affect the structural integrity of the filter element. In another embodiment, the filter element is securely engaged to support device 330 by heating one or more heat activated adhesives at least disposed between the perimetral ledge of the filter element and first surface 333. In other embodiments, the filter element is coupled to the support device 330 according to ways known to a person skilled in the art.

Referring to FIG. 7, support device 330 which is coupled with a filter element (not shown) is inserted into the beverage container 300. The support device 330 is coupled to the inner surface 320 b of the sleeve 320. Specifically, the recess 336 a receives protrusion 325, thereby securely engaging the support device 330 to the inner surface 320 b of the sleeve 320. As depicted in FIG. 3(a), when the support device 330 is securely engaged to the inner surface 320 b, the protrusion 325 resides within recess 336 a such that recess lip 336 b directly opposes protrusion surface 325 a and recess lip 336 c directly opposes protrusion surface 325 b. The secured support device 330 coupled with the filter element separates the beverage cartridge into two chambers: a first chamber 370 and a second chamber 380.

Dry beverage ingredients (not shown) are then inserted into first chamber 370 and are prevented from entering the second chamber 380 by support device 330 and the filter element. Lid 360 is then coupled to the outer container 310. Specifically, heat-activated adhesive is disposed on top perimetral rim 311. The lid 360 is placed over the heat-activated adhesive, and heat is applied to securely engage the lid 360 to the outer container 310. In other embodiments, lid 360 is securely engaged to the beverage cartridge 300 by friction fit to the inner surface 320 b of the beverage cartridge 300, or any other ways known to a person skilled in the art.

In other embodiments, the filter element is coupled to the support device after the support device is securely engaged to the inner surface of beverage cartridge.

Manufacture of Beverage Cartridge

Using an example where an outer container does not form a part of the beverage container, a sleeve is manufactured by vacuum forming. The formed sleeve comprises: (i) a top perimetral ledge adapted for engaging the lid; (ii) an opening that is surrounded by the top perimetral ledge; (iii) a base; and (iv) a side wall that extends between the base and the top perimetral ledge. In addition, the sleeve comprises one or more protrusions that extend toward the centre of the sleeve.

A support device is manufactured by injection molding. The formed support device comprises one or more recesses adapted for receiving the one or more protrusions of the sleeve. The formed support device may be device 100, device 200, or any embodiment thereof.

A filter element is coupled to the support device by melting the surfaces of the support device and adhering the filter element to the melted surfaces, heat-activated adhesives, or other ways known to a person skilled in the art.

The support device which is coupled with the filter element is inserted into the sleeve, and coupled to the inner surface of the sleeve. Specifically, the one or more recesses receives the one or more protrusions, thereby securely engaging the support device to the inner surface of the sleeve. The secured support device coupled with the filter element separates the sleeve into two chambers: a first chamber and a second chamber.

Dry beverage ingredients (not shown) are then inserted into the first chamber and are prevented from entering the second chamber by the support device and the filter element. A lid is then coupled to the outer container.

Use of the Beverage Cartridge 300

Using beverage cartridge 300 as an example, beverage cartridge 300 is inserted into a compartment of a brewing machine. The brewing machine is activated. A fluid injector penetrates through the lid 360 and into first chamber 370, the first chamber 370 containing the dry beverage ingredients. The fluid injector does not touch the filter element. A fluid extractor penetrates through base 314 of the outer container 310 and base 323 of sleeve 320 and into the second chamber 380. The fluid extractor does not touch filter element 350. A brewing medium (e.g. hot water) is expelled from the fluid injector and into the first chamber 370. The brewing medium mixes with the beverage ingredients, and flavours from the beverage ingredients are extracted into the brewing medium. The brewing medium containing the extracted flavours percolates through the filter element and into second chamber 380. The fluid extractor extracts the brewing medium containing the extracted flavours from second chamber 380. The brewing medium containing the extracted flavours is then dispensed from the brewing machine as a drink beverage. The used beverage cartridge is expelled from the brewing machine and into a residential compost bin for residential composting.
